[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0059] Based on the problems mentioned in the foregoing background technology, in the related art, for the control of the active suspension, it is mostly used to reduce the bumpiness of vehicle driving, lacking the consideration of vehicle usage scenarios, making the suspension adjustment relatively single and the vehicle usage convenience relatively poor.

[0060] To solve the above problems, the embodiments of the present application propose a suspension adjustment method, a controller, a medium, a program product, and a vehicle. The embodiments of the present application can adjust the suspension through the tailgate switch state, cooperate with the vehicle loading scenario to adjust the vehicle suspension, and improve the vehicle usage convenience.

[0061] Specifically, the suspension adjustment method in the present application can be applied to a vehicle, and the execution subject can be a controller on the vehicle. Subsequently, taking the execution subject of the suspension adjustment method as the controller on the vehicle as an example, each embodiment will be described in detail.

[0062] The present application provides a suspension adjustment method. Please refer to Figure 1 , the suspension adjustment method provided by the embodiments of the present application includes step S10 - step S20, which will be introduced in detail below.

[0063] S10. Obtain the tailgate switch state of the vehicle.

[0064] In this embodiment, the vehicle tailgate is a movable part at the rear of the vehicle, mainly used to close and open the trunk space of the vehicle for loading. The tailgate switch state is used to indicate the tailgate switch situation, such as open and closed.

[0065] S20. Adjust the suspension height of the vehicle according to the tailgate switch state.

[0066] In this embodiment, the vehicle suspension is controlled according to the tailgate switch state, and the suspension height is adjusted so that the suspension height can adapt to the tailgate switch state, cooperate with the user for loading operations, and improve the user operation convenience. Moreover, when the tailgate is opened, the center of gravity at the rear of the vehicle may change, resulting in unstable vehicle body posture. Adjusting the suspension height according to the tailgate switch state can also maintain the balance and stability of the vehicle body.

[0067] In one embodiment, the vehicle suspension adjusted according to the tailgate switch state is the suspension of the axle closest to the tailgate, that is, the vehicle rear axle suspension. The rear axle suspension refers to the suspension installed on the rear axle of the vehicle, so as to cooperate with the tailgate to facilitate the user to pick up items.

[0068] In one embodiment, obtaining the tailgate switch state of the vehicle tailgate includes:

[0069] Obtaining the tailgate switch state through the hard-wired switch of the tailgate.

[0070] In this embodiment, the hard-wired switch refers to the tailgate switch directly connected to the suspension adjustment unit (which can be an ECU) through a physical line. When the user presses the tailgate switch, the hard-wired switch generates an electrical signal. This signal is usually a high-level or low-level signal, depending on the design of the switch, so that the tailgate switch signal is transmitted through the hard wire (physical line).

[0071] In this embodiment, directly adjusting the vehicle suspension height by directly linking with the hard-wired switch of the tailgate can obtain the tailgate switch state through the tailgate switch signal sent by the received tailgate hard-wired switch, which can improve the suspension adjustment efficiency and reduce the development cost.

[0072] In one embodiment, the method further includes:

[0073] When the voltage ratio of the first battery of the vehicle is greater than the preset voltage ratio, adjusting the suspension height of the vehicle according to the tailgate switch state.

[0074] In this embodiment, it is determined whether to adjust the vehicle suspension according to the tailgate switch state based on whether the voltage ratio of the first battery of the vehicle is greater than the preset voltage ratio. The first battery can be the large battery of the vehicle. The large battery system controls the high voltage of the whole vehicle. The voltage ratio is a threshold value used by the external system for judgment. High-power work cannot be performed below the threshold value. When the ratio of the first battery is greater than the preset power ratio, the tailgate switch state can be the electrical state, wireless state, etc. generated during the opening and closing of the vehicle tailgate, which can ensure the vehicle's power consumption safety and avoid vehicle power failure.

[0075] In one embodiment, the method further includes:

[0076] When the voltage ratio of the first battery of the vehicle is greater than the preset voltage ratio, obtaining the voltage value of the second battery of the vehicle;

[0077] When the voltage value of the second battery is greater than the target preset voltage threshold, adjusting the suspension height of the vehicle according to the tailgate switch state.

[0078] In this embodiment, when the voltage ratio of the first battery of the vehicle is greater than the preset voltage threshold, it is necessary to further obtain the voltage value of the second battery of the vehicle, and determine whether to adjust the vehicle suspension according to the tailgate switch state based on whether the second voltage value is greater than the target preset voltage threshold. The second battery can be the small battery of the vehicle, and the small battery is used to control the vehicle's constant power supply. It is difficult for the voltage of the vehicle's large battery to drop below the set threshold. By charging the vehicle, the situation of large battery power feeding can be avoided. After the large battery system detects that the voltage of the small battery is lower than the set threshold, it will automatically charge the small battery to make the small battery meet the vehicle working voltage and prevent the vehicle from entering the power feeding state. The voltage value of the second battery can represent an external signal. Based on the characteristics of the external signal, it can be determined whether the current voltage value of the second battery can meet the motor work. Therefore, when the voltage ratio of the first battery is greater than the preset voltage threshold and the voltage value of the second battery is greater than the target preset voltage threshold, the vehicle suspension can be adjusted according to the tailgate switch state to further ensure the vehicle's power consumption safety and avoid vehicle power feeding.

[0079] In this embodiment, through the double verification of the first battery and the second battery, the judgment logic for whether to adjust the vehicle suspension height based on the tailgate switch state is optimized, effectively avoiding the risk of vehicle power feeding. The optimized suspension adjustment trigger condition in this embodiment does not require the air source of the airbag. Before adjusting the suspension, by judging the voltage, the suspension pump can be directly activated to lift, improving the control efficiency and further providing the convenience of use.

[0080] In one embodiment, the steps for determining the target preset voltage threshold include:

[0081] Obtain the ambient temperature corresponding to the second battery;

[0082] Determine the target preset voltage threshold according to the ambient temperature.

[0083] In this embodiment, for the threshold setting of the voltage value of the second battery, it can also be set in combination with the ambient temperature corresponding to the second battery. The ambient temperature corresponding to the second battery can refer to the temperature near the second battery or the ambient temperature of the vehicle where the second battery is located. The ambient temperature corresponding to the second battery directly affects the power consumption performance of the battery. Determining the target preset voltage threshold based on the ambient temperature corresponding to the second battery can avoid directly designing the critical value for the environment. Different target preset voltage thresholds can be designed under different ambient temperatures for conditional substitution, avoiding the influence of temperature on suspension adjustment and taking objects through the tailgate, and further improving the convenience of vehicle use.

[0084] In one embodiment, the determining the target preset voltage threshold according to the ambient temperature includes:

[0085] Determine the target preset voltage threshold corresponding to the ambient temperature according to the correspondence between the preset temperature range and the preset voltage threshold.

[0086] In this embodiment, at least one preset temperature range can be preset in advance. For different preset temperature ranges, corresponding preset voltage thresholds are set, so that in different temperature environments, the suspension height can be adjusted based on the tailgate switch state within an appropriate voltage value of the second battery. Determine the preset temperature range where the ambient temperature is located, and use the preset voltage threshold corresponding to the preset temperature range where it is located as the target preset voltage threshold corresponding to the ambient temperature.

[0087] In one embodiment, the preset temperature range includes a first temperature range and a second temperature range. The minimum temperature in the first temperature range is greater than or equal to the preset temperature value, and the maximum temperature in the second temperature range is less than the preset temperature value.

[0088] In this embodiment, at least two preset temperature ranges are set, namely the first temperature range and the second temperature range. Among them, the minimum temperature in the first temperature range is greater than or equal to the preset temperature value, and the maximum temperature in the second temperature range is less than the preset temperature value, so that the first temperature range and the second temperature range are bounded by the preset temperature value. When the ambient temperature is greater than or equal to the preset temperature value, the preset voltage threshold corresponding to the first temperature range can be used as the target preset power threshold. When the ambient temperature is less than the preset temperature value, the preset voltage threshold corresponding to the second temperature range can be used as the target preset power threshold. It can be understood that the preset voltage threshold corresponding to the first temperature range is different from the preset voltage threshold corresponding to the second temperature range, so that judging whether to adjust the suspension height according to the voltage will not be affected by the ambient temperature, improving control accuracy and use convenience.

[0089] In one embodiment, the method further includes:

[0090] When the vehicle speed of the vehicle is less than the preset vehicle speed, adjust the suspension height of the vehicle according to the tailgate switch state.

[0091] In one embodiment, adjusting the vehicle suspension according to the tailgate switch state is a more direct control method, which can improve control efficiency. Therefore, before adjusting the vehicle suspension according to the tailgate switch state, the vehicle speed of the vehicle can be obtained periodically or in real time. When the vehicle speed is less than the preset vehicle speed, adjusting the vehicle suspension according to the tailgate switch state can avoid controlling the suspension in some unexpected situations. For example, during the vehicle driving process, the tailgate pops open due to bumps and mis-controls the suspension, which can improve vehicle safety.

[0092] In one embodiment, the method further includes:

[0093] When a target body covering of the vehicle is closed, the suspension height of the vehicle is adjusted according to the tailgate switch state, wherein the target body covering includes at least one of a vehicle door, a front hood, and a door of an on-board unmanned vehicle cabin.

[0094] In this embodiment, before adjusting the vehicle suspension according to the tailgate switch status, it is also necessary to obtain the switch status of the vehicle's target body coverings, the target body coverings including at least one of the vehicle doors, the front hood and the hatches of the on-board unmanned cabin. When the vehicle's target body coverings are closed, controlling the vehicle's suspension according to the tailgate switch status can avoid vehicle instability due to suspension adjustment, resulting in damage to the target body coverings due to bumps, etc., and can further improve vehicle safety.

[0095] In one embodiment, adjusting the suspension height of the vehicle according to the tailgate switch state includes:

[0096] When the tailgate switch is in the open state, the suspension height of the vehicle is lowered.

[0097] In this embodiment, when the above conditions are met, the suspension can be adjusted according to the tailgate switch state. When the tailgate switch state is open, it indicates that the user has a need to pick up something, and the suspension can be adjusted to lower the vehicle's suspension height, so that the overall height of the vehicle is lowered, which is convenient for the user to pick up something and improves the convenience of picking up something. In addition, the user's need to pick up something will cause the center of gravity of the vehicle to be unstable. After adjusting the suspension to lower, the stability of the vehicle can be improved.

[0098] In one embodiment, lowering the suspension height of the vehicle comprises:

[0099] The height regulating valve corresponding to the suspension is controlled to be opened, and the pump motor corresponding to the suspension is controlled to be in a closed state, so that the suspension is lowered.

[0100] In this embodiment, a design principle for adjusting the height of the suspension by the pump motor and the height adjustment valve of the suspension is provided. When lowering the height of the suspension of the vehicle, the height adjustment valve corresponding to the suspension is controlled to open, the pressure inside the suspension is released, and the suspension is gradually lowered due to the weight of the vehicle. At this time, the pump motor corresponding to the suspension needs to be adjusted to be in a closed state to quickly lower the height of the suspension.

[0101] In one embodiment, after controlling the height adjustment valve corresponding to the suspension to be opened and controlling the pump motor corresponding to the suspension to be in a closed state, the method further includes:

[0102] When the suspension is lowered to a preset height, the height regulating valve corresponding to the suspension is controlled to be closed to maintain the height of the suspension.

[0103] In this embodiment, when the suspension is lowered to a preset height, which can be the lowest gear of the vehicle suspension, the height regulating valve corresponding to the suspension is controlled to close to maintain the height of the suspension, so as to help the user pick up objects with a lower suspension height and improve the convenience of use.

[0104] In one embodiment, the method further includes:

[0105] When the real-time height of the suspension is greater than the preset height, lower the suspension height of the vehicle.

[0106] In this embodiment, before adjusting the suspension to lower, it is also necessary to detect whether the real-time height of the suspension is greater than the preset height. When the real-time height of the suspension is greater than the preset height, it indicates that the vehicle suspension height is already low and there is no need to control the lowering anymore, which saves control costs and avoids unnecessary collisions after the vehicle is triggered to lower.

[0107] In one embodiment, after lowering the suspension height of the vehicle, it further includes:

[0108] When the tailgate switch state of the tailgate is closed, raise the suspension height of the vehicle.

[0109] In this embodiment, after the tailgate switch state is opened and waiting for the user to complete the object picking operation, the tailgate will be closed. When the tailgate switch state is opened and the suspension height of the vehicle is lowered, and it is detected that the tailgate switch state is closed, it is necessary to raise the vehicle suspension height to end the vehicle object picking process, which facilitates the subsequent operation of the vehicle at the normal suspension height and further ensures vehicle safety.

[0110] In one embodiment, raising the suspension height of the vehicle includes:

[0111] Control the height regulating valve corresponding to the suspension to open, and control the pump motor corresponding to the suspension to be in the starting state to raise the suspension height.

[0112] In this embodiment, during the process of raising the vehicle suspension height, it is necessary to control the height regulating valve corresponding to the suspension to open, and control the corresponding pump motor to be in the starting device to provide pressure inside the suspension so that the vehicle suspension can be raised.

[0113] In one embodiment, after controlling the height regulating valve corresponding to the suspension to open and controlling the pump motor to be in the starting state, it further includes:

[0114] When the suspension is raised to the height before the suspension is lowered, control the height regulating valve corresponding to the suspension to close to maintain the height of the suspension.

[0115] In this embodiment, during the process of adjusting the vehicle suspension to rise, it is detected whether the suspension has risen to the height before the suspension was lowered. When the suspension has risen to the height before the suspension was lowered, it indicates that the suspension height has been restored to the height before lowering. The height regulating valve corresponding to the suspension can be controlled to close to maintain the suspension height, complete the restoration of the suspension height after taking an object, facilitate the subsequent normal operation of the vehicle, ensure vehicle safety, and reduce the need for users to perform additional operations, further improving the usability.

[0116] In one embodiment, the method further includes:

[0117] When the suspension has risen to the height before the suspension was lowered, control the pump motor corresponding to the suspension to close.

[0118] In this embodiment, when the suspension has risen to the height before the suspension was lowered, on the one hand, the height regulating valve corresponding to the suspension can be controlled to close to maintain the suspension height, and on the other hand, the pump motor corresponding to the suspension can be controlled to close to avoid waste of resources.

[0119] In one embodiment, the method further includes:

[0120] When the real-time height of the suspension is less than the height before the suspension was lowered, raise the suspension height of the vehicle.

[0121] In this embodiment, before adjusting the suspension to rise, it is also necessary to detect whether the real-time height of the suspension is less than the height before lowering. When the real-time height of the suspension is less than the height before lowering, it indicates that the vehicle suspension height has been restored and there is no need to control the lowering anymore, which can save control costs.

[0122] In one example, as Figure 2 shown, the present invention provides a method. After the vehicle enters the sleep state, a tailgate switch signal indicating that the tailgate is opened is obtained through the hard wire switch of the tailgate, indicating that the tailgate switch state is open, waking up the vehicle domain control system. After the domain control system is woken up by the hard wire, a preset wake-up message 1 is sent to wake up the system of the large battery of the vehicle, a preset wake-up message 2 is sent to wake up the system of the small battery, and a preset wake-up message 3 is sent to wake up the suspension adjustment system. The suspension adjustment system obtains the voltage ratio of the large battery to determine whether it supports suspension height adjustment, obtains the voltage value of the small battery, and the ambient temperature to determine whether it supports suspension height adjustment. The suspension adjustment system obtains the switch states of the doors, the front hood, etc. and the vehicle speed state to determine whether it supports suspension height adjustment. When the target conditions are met, the rear axle suspension height is adjusted to lower to the low gear operation, achieving the effect of automatically lowering the suspension when the tailgate is opened.

[0123] As Figure 3As shown, after the vehicle is woken up and the user has finished using the fetching function and closes the tailgate through the tailgate button, the suspension adjustment system can receive the tailgate switch signal indicating that the tailgate is closed, indicating that the tailgate switch state is closed. The suspension adjustment system obtains the voltage ratio of the large battery to determine whether suspension height adjustment is supported, and obtains the voltage value of the small battery and the ambient temperature to determine whether suspension height adjustment is supported. When the conditions are met, the suspension executes the restoration operation of raising the suspension, achieving the effect of automatically restoring the suspension by closing the tailgate. After there is no other operation on the vehicle and the vehicle has been placed for a period of time, it re-enters the sleep state.

[0124] In one example, as Figure 4 shown:

[0125] 1) After the suspension adjustment system is woken up by a message, the suspension adjustment system periodically detects the tailgate switch state. When an external tailgate switch signal is detected, the tailgate switch state is determined and the next step is executed.

[0126] 2) The suspension adjustment system obtains the specific message 1 forwarded by the gateway in a loop to detect the voltage ratio of the large battery. When the voltage ratio of the large battery is lower than the preset voltage ratio, suspension adjustment is prohibited. When the voltage ratio of the large battery is higher than the preset voltage ratio, the next step is executed.

[0127] 3) The suspension adjustment system obtains the specific message 2 forwarded by the gateway in a loop to detect the voltage value of the small battery and the ambient temperature value to identify whether the execution conditions are met. Condition 1: When the ambient temperature is greater than the preset temperature, check whether the voltage value of the small battery is greater than the target preset voltage threshold 1, and both judgments need to be established. Condition 2: When the ambient temperature is less than the preset temperature, check whether the voltage value of the small battery is greater than the target preset voltage threshold 2, and both judgments need to be established. If either of the above two conditions is met, the next step is executed.

[0128] 4) The suspension adjustment system determines the tailgate switch state. When the tailgate switch signal indicates that the tailgate is open, the tailgate opens and the suspension adjustment system responds by lowering the rear suspension to the low gear operation. When the tailgate switch signal indicates that the tailgate is closed, the tailgate closes and the suspension adjustment system responds by restoring the rear suspension to the state before lowering.

[0129] In one example, the process of adjusting the suspension to lower, as Figure 5 shown:

[0130] 1) Before adjusting the suspension to lower, periodically detect the vehicle speed state. When the vehicle speed is greater than the preset vehicle speed, the suspension adjustment function is not executed. When the vehicle speed is less than or equal to the preset vehicle speed, the next operation is executed.

[0131] 2) Periodically detect the signals of the four vehicle doors and the front hood to determine their corresponding switch states. When the feedback of the state of one of the doors or the front hood is in the open state, the suspension adjustment function is not executed. When the signals of the four vehicle doors and the front hood simultaneously meet the closed condition, the next operation is performed.

[0132] 3) Obtain the height gear of the vehicle's rear axle suspension. If the real-time gear is equal to the preset gear height range that needs to be lowered, the suspension adjustment function is not executed. Otherwise, control the pump motor to turn off and simultaneously open the height regulating valve of the rear axle suspension.

[0133] 4) The suspension system continuously detects the suspension height. When it detects that the suspension height is within the preset gear height range of lowering, close the height regulating valve of the rear axle suspension and maintain the rear axle suspension height at the current state.

[0134] 5) Complete the operation of lowering the rear axle suspension to the low gear.

[0135] In one example, the process of adjusting the suspension to rise is as Figure 6 shown:

[0136] 1) Before adjusting the suspension to rise, periodically detect the vehicle speed signal to determine the vehicle speed. When the vehicle speed is greater than the preset vehicle speed, the suspension adjustment function is not executed. When the vehicle speed is less than or equal to the preset vehicle speed, the next operation is performed.

[0137] 2) Periodically detect the signals of the four vehicle doors and the front hood to determine their switch states. When the feedback of the state of one of the doors or the front hood is in the open state, the suspension adjustment function is not executed. When the states of the four vehicle doors and the front hood simultaneously meet the closed condition, the next operation is performed.

[0138] 3) Obtain the height gear of the vehicle's rear axle suspension. If the real-time gear is equal to the target gear height range of restoration, the suspension adjustment function is not executed. Otherwise, control the pump motor to turn on and simultaneously open the height regulating valve of the rear axle suspension.

[0139] 4) The suspension system continuously detects the suspension height. When it detects that the suspension height is within the target gear height range of restoration, close the height regulating valve of the rear axle suspension and the pump motor, and maintain the rear axle suspension height at the current state.

[0140] 5) Complete the operation of raising the rear axle suspension to the restored position.

[0141] This embodiment also provides an electronic device, which can be specifically integrated in a vehicle. The electronic device may include:

[0142] An acquisition module, configured to acquire the tailgate switch state of the vehicle's tailgate;

[0143] A control module, configured to adjust the suspension height of the vehicle according to the state of the tailgate switch.

[0144] For the specific implementation of each of the above operations, reference may be made to the previous embodiments, which will not be elaborated herein.

[0145] Correspondingly, an embodiment of the present application further provides a controller, as Figure 7 shown, Figure 7 is a schematic structural diagram of the controller provided by the embodiment of the present application. The controller 1100 further includes a processor 1101 having one or more processing cores, a memory 1102 having one or more computer-readable storage media, and a computer program stored on the memory 1102 and executable on the processor. Among them, the processor 1101 is electrically connected to the memory 1102. Those skilled in the art can understand that the controller structure shown in the figure does not constitute a limitation on the controller, and may include more or fewer components than shown, or combine certain components, or arrange different components.

[0146] The processor 1101 is the control center of the controller 1100, connecting various parts of the entire controller 1100 through various interfaces and lines. By running or loading software programs and / or units stored in the memory 1102, and calling data stored in the memory 1102, the processor 1101 executes various functions of the controller 1100 and processes data, thereby performing overall monitoring of the controller 1100. The processor 1101 may be a central processing unit (CPU), a graphics processing unit (GPU), a network processor (NP), etc., and can implement or execute the various methods, steps, and logic block diagrams disclosed in the embodiments of the present application.

[0147] In the embodiment of the present application, the processor 1101 in the controller 1100 will load the instructions corresponding to the processes of one or more application programs into the memory 1102 according to the following steps, and the processor 1101 will run the application programs stored in the memory 1102 to implement various functions, such as:

[0148] Obtain the state of the tailgate switch of the vehicle;

[0149] Adjust the suspension height of the vehicle according to the state of the tailgate switch.

[0150] For the specific implementation of each of the above operations, reference may be made to the previous embodiments, which will not be elaborated herein.

[0151] Optionally, as Figure 7As shown, the controller 1100 further includes: a touch display screen 1103, a radio frequency circuit 1104, an audio circuit 1105, an input unit 1106, and a power supply 1107. Among them, the processor 1101 is electrically connected to the touch display screen 1103, the radio frequency circuit 1104, the audio circuit 1105, the input unit 1106, and the power supply 1107 respectively. Those skilled in the art can understand that Figure 7 the controller structure shown in

[0152] does not constitute a limitation on the controller, and may include more or fewer components than shown in the figure, or combine certain components, or have different component arrangements. The touch display screen 1103 can be used to display a graphical user interface and receive operation instructions generated by the user acting on the graphical user interface. The touch display screen 1103 may include a display panel and a touch panel. Among them, the display panel can be used to display information input by the user or information provided to the user, as well as various graphical user interfaces of the controller. These graphical user interfaces can be composed of graphics, text, icons, videos, and any combination thereof. Optionally, the display panel can be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), etc. The touch panel can be used to collect touch operations of the user on or near it (such as operations of the user using a finger, a stylus, or any suitable object or accessory on or near the touch panel), and generate corresponding operation instructions, and the operation instructions execute the corresponding program. Optionally, the touch panel can include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the touch position of the user and detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into touch point coordinates, and then sends it to the processor 1101, and can receive and execute the command sent by the processor 1101. The touch panel can cover the display panel. When the touch panel detects a touch operation on or near it, it transmits it to the processor 1101 to determine the type of touch event. Subsequently, the processor 1101 provides a corresponding visual output on the display panel according to the type of touch event. In the embodiment of the present invention, the touch panel and the display panel can be integrated into the touch display screen 1103 to achieve input and output functions. However, in some embodiments, the touch panel and the touch panel can be implemented as two independent components to achieve input and output functions. That is, the touch display screen 1103 can also be used as a part of the input unit 1106 to achieve the input function.

[0153] The radio frequency circuit 1104 can be used to transmit and receive radio frequency signals to establish wireless communication with network medical devices or other controllers through wireless communication, and transmit and receive signals with network medical devices or other controllers.

[0154] The audio circuit 1105 can be used to provide an audio interface between the user and the controller through a speaker and a microphone. The audio circuit 1105 can transmit the electrical signal converted from the received audio data to the speaker, which converts it into a sound signal for output; on the other hand, the microphone converts the collected sound signal into an electrical signal, which is received by the audio circuit 1105 and then converted into audio data. After the audio data is output to the processor 1101 for processing, it is sent by the radio frequency circuit 1104 to, for example, another controller, or the audio data is output to the memory 1102 for further processing. The audio circuit 1105 may also include an earphone jack to provide communication between a peripheral earphone and the controller.

[0155] The input unit 1106 can be used to receive input digital, character information or user characteristic information (such as fingerprint, iris, face information, etc.), and generate keyboard, mouse, joystick, optical or trackball signal inputs related to user settings and function controls.

[0156] The power supply 1107 is used to supply power to each component of the controller 1100. Optionally, the power supply 1107 can be logically connected to the processor 1101 through a power management device, so as to realize functions such as management of charging, discharging, and power consumption management through the power management device. The power supply 1107 may also include any components such as one or more DC or AC power supplies, a recharge device, a power failure detection circuit, a power converter or inverter, and a power status indicator.

[0157] Although Figure 7 not shown in the figure, the controller 1100 may also include a camera, a sensor, a Wi-Fi module, a Bluetooth module, etc., which will not be elaborated here.
